Buck hit .333 with 6 HR and 19 RBI in the first 12 games of this season. However, he's batting .160 in his last six games.
He'll be an interesting case. As Olney points out, I can totally see Sandy Alderson hanging on to Buck. By mid season he will likely return to being the defensively-sound, veteran leader with occasional power, which he's been for most of his career. And, he'll be doing this while having roughly $3 million left on his contract this season.
I'm not sure what a team will be willing to give up for his situation. I have no idea what the market is going to be like, but my hunch is that Buck's market value will pale in comparison to keeping Buck's leadership for Harvey, Zack Wheeler and Travis d'Arnaud (both of whom will likely be promoted by then).
